TTYs for the deaf

Hello folks,

I have a question about those TTYs that the deaf use. Are they real
Teletypes, like ASR33 and friends, or not? I guess probably not, because
it would be so super-cool if they were that it's probably too good to
be true, but I thought I would ask anyway. So what are they? Are they
normal ASCII terminals with standard modems built in, or something
entirely different? Can one pretend to be deaf, go to some social service
or whatever agency asking to use a deaf TTY, and dial into a timesharing
host or BBS with it?

It also seems like there are two kinds of deaf devices, TTY and TDD.
What's the difference?
